What our data cleaning services include
Every job starts with your files as they are. Then we work through each of these steps so the result is ready to use.
- Excel and CSV data cleaning
We fix inconsistent names, spacing, capital letters and text stored as numbers, so every column behaves the way it should.
- Duplicate removal
We find exact and near-duplicate records, for example the same customer typed two ways, and keep one correct row.
- Data formatting and standardization
Dates, currencies, phone numbers and regions then follow one format. As a result, sorting and filtering finally work.
- Missing-data identification
Blank or impossible values are flagged rather than hidden. That way you can decide how to fill or exclude them.
- Data validation and quality checks
We test totals, ranges and record counts against your source so nothing is lost during cleaning.
- Data consolidation from multiple files
Branch, monthly or departmental files are combined into one table, so every column finally matches.
- Preparing datasets for reporting and analysis
Finally, we shape the data into a layout that Excel pivot tables and Power BI can read straight away.
Why clean data comes first
Every report depends on the data underneath it. When a sales export contains duplicates, the totals look higher than they really are. Similarly, when dates come in three formats, monthly trends break. So most reporting problems are really data problems.
Our data cleaning services therefore fix the problem at the source. We follow well-known data cleansing practice and use tools such as Excel and Power Query. Because the steps are recorded, the same cleaning can also run again next month.
Signs you need data cleaning
- Totals change depending on who prepares the report
- The same customer or product appears under different names
- Dates and amounts will not sort or add up correctly
- You spend hours copying data between files before you can start

Questions about data cleaning services
How much data can you clean?
Anything from a single sheet to many files with thousands of rows. Send a sample first, and then we will confirm the scope.
Will you change my original files?
No. We work on a copy and return a new clean file, so your originals stay exactly as they were.
Can the cleaning be repeated every month?
Yes. When your data arrives in the same layout each month, we can set up Power Query steps that clean it automatically.
Is my data kept confidential?
Yes. We only use your files for the agreed work, and we can explain how to share them safely before you send anything.
